Abstract
A technology for shaping the blank of shaped nut includes simulating the deformation rationality of each station by software, calculating the blank volume of each station, shearing, blanking, shaping to remove pits and burr, deep drawing for shaping the blank, and extruding the blank. The cold heading direct forming can be realized, the turning allowance of machining is reduced, the production efficiency of products is improved, and the production period of the products is shortened.
Description
Technical Field
The invention belongs to the technical field of hardware parts and accessories, and particularly relates to a forming process of a special-shaped nut blank.
Background
Various hardware parts are generally used in the mechanical industry for machining and installation, for example, a fastener is a common hardware part and is a general term for a type of mechanical parts used when two or more parts or components are fastened and connected into a whole. The nut is a common fastener, and the conventional nut is a square or hexagonal nut and has a simple structure. The complex special-shaped nut is mostly finished by adopting a machining mode, the complex special-shaped nut needs to be finished by working procedures of turning, milling, drilling, boring and the like, the production efficiency is low, the utilization rate of raw materials is low, and the complex special-shaped nut is not suitable for industrial mass production.
Disclosure of Invention
The invention aims to provide a forming process of a special-shaped nut blank aiming at the technical defects of low utilization rate of raw materials and low production efficiency in the existing nut manufacturing process, which can be used for directly forming by cold heading, reduces the turning allowance of machining, improves the production efficiency of products and shortens the production period of the products.
Technical scheme
In order to achieve the technical purpose, the invention provides a forming process of a special-shaped nut blank, which is characterized by comprising the following steps of:
(1) simulating the deformation rationality of each station by simulation software, and calculating the blank volume of each station;
(2) shearing and blanking;
(3) shaping the blank material obtained in the step 2) to remove pits and burrs;
(4) carrying out deep hole drawing forming on the blank obtained in the step (3);
(5) extruding the blank obtained in the step (4), thereby realizing the forming of deep holes and shallow holes;
(6) shaping the blank obtained in the step (4).
Advantageous effects
The forming process of the special-shaped nut blank provided by the invention can be used for directly forming by cold heading, reduces the turning allowance of machining, improves the production efficiency of products and shortens the production period of the products.
